The minimum breakdown voltage is 432 V, so the avalanche threshold sits about 11 % above the standoff level — a typical margin for TVS diodes guarding 380 V DC bus or 277 V AC line applications (the peak of 277 V RMS is ~392 V, just above the standoff). ## Through-hole DO-201AA axial — hand-solderable, board-mount Packaged in a DO-201AA (DO-27) axial-lead through-hole case, the 1.5KE480-/54 is straightforward to hand-solder or wave-solder into a PCB. The axial leads fit standard 0.100-inch pitch holes and the body is large enough to read the marking without magnification — a practical choice for bench repair, prototyping, or low-volume production where rework matters.","metaTitle":"1.5KE480-E3/54, Vishay TransZorb TVS, 1500W, 389V Standoff","metaDescription":"Obsolete Vishay 1.5KE480-E3/54 TransZorb TVS diode, 1500W peak pulse, 389V standoff, DO-201AA axial.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Vishay General Semiconductor - Diodes Division","Type":"Zener","Series":"TransZorb®","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Through Hole","Package / Case":"DO-201AA, DO-27, Axial","Product Status":"Obsolete","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5KE480","Operating Temperature":"-55°C~175°C(TJ)","Power Line Protection":"No","Capacitance @ Frequency":"-","Supplier Device Package":"1.5KE","Unidirectional Channels":"1","Voltage - Breakdown (Min)":"432V","Voltage - Clamping (Max) @ Ipp":"686V","Voltage - Reverse Standoff (Typ)":"389V","Current - Peak Pulse (10/1000µs)":"2.19A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cbd949ebcf4c95d5b4ea8fdecf87536f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the 1.5KE480-/54?","answer":"Because it is obsolete, stock is lot-specific — send a request for current availability and pricing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE480-E3-54","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/vishay-general-semiconductor-diodes-division/1.5KE480-E3-54 when reusing this data.
